'. To all 'whom may concern:

' 1 Be it known that I, WALTER ll. Guess, a

,citiren 'of the United States,'residing nl (hi- 5. I useful Improvementin Waterduriiiers, of

cage Hei hts, in the county of (Took and State of. linois,.have inventeda new and which the following is a specification.

My invention relates to an improvement in i '1 apparatus forpurifying-or softening, water for industrial purposes; and the primaryob. j'ct of my improvement is to enable the apparatus to be sosimplified in construction as to avoid all necessity of frequentlyclimbing 3 on Fi 2, and viewed in the direction of the I arrow fFig. 4 abroken and partly sectional view on hne. 4 of Fi 5, of one form of themeans, I have deviser for automaticall proportioning the feed of thechemical so ution to that of the water under'treatment, and showing-thedevice in its position relative to an overflowsrcceptacle; Fig. 5, abroken view of the same in end elevation, showing one position by dottedrepresentation; Fig. '6, a section taken at the line 6 on Fig. 4, andviewed in the direction of the arrow; Fig. 7, a broken view inelevationshowing a modified construction of the device illustrated in Fig. 4, andFig.8, a similar view of the same regarded in the direction of the arrowin Fig. 7.

i 16 fulcrumed at its opposite end onastand shown to be equipped with aslide-valve 19 The precipitating-tank 9 equipped with an overflow 10near its upper end and a valved pipe 11 on its bottom for drawing oilsludge and containing a downtake-conduit 12 presents, no features ofnovelty; and the same is true of the water-box 13 surmounting theprecipitating-tank and in which a float 14 is suspended by a rod 15 fromone end of a lever ard 17. In a side of the box 13 near its bot-'- tomis provided a discharge opening in through which to direct the raw waterinto the top of the conduit 12, and this opening is for regulating t 1earea of the discharge-opening. The valve is, however, an unnecessaryfeature inasmuch as when it is once set for a given size of apparatus itneed never be changed, the only advantage in providing the valve beingthat it enables a stock of similar water-boxes to be manufactured andkept, from which to e uip water-softening plants of varying sizes. yadjusting the valves to such sizes.

The raw water to be treated is supplied from any suitable source andintroduced, as through the medium of a pump represented at20'discharging through a pipe 21, into the box 13 at its open top. Thechemical solution is contained in a tank 22 shown to besupported at thebase of the settling-tank 9, though it may be supported in any otherpo-, sition desired. The solution is fed to the tank 9 through a pipe 23in which a plump 24 is shown to be'interposed; and anot er ipe 25surmounted by a receptacle 26 leads the latter to the tank 22 to returninto it and thus save the overflow of the solution.

As represented in Figs. 1, 4 and 5, the ipe 23 above the top of thesettling-tank is nt to a right-angle to form a horizontal tubular BESTAVAILABLE COPY arm 27 containing a lateral elongated slot the arm andconnected from its free end b a link 32 with the lever 16. The adjust-ale extension 31, which automatically maintains the head of the solutionin correspondence with that of the water in the box 13, is directlyabove the rece )tacle 26.

In the operation of t c apparatus the raw water to be treated enters thebox 13 through the pipe 21 and discharges through the opening 18 in thelatter into the downtake-conduit 12 while the chemical solution entersthat conduit from the pipe 23 through the discharge-slot-28 to mix withthe water for its reaction thereon. Any increase or decrease in the rateof flow through the pipe 21, under variation in the operation of the um20, will raise'or lower the level of water in the box 13, therebyvarying the head thereof and raising or lowering the float 14correspondingly. As the float rises or falls it moves the lever 16accordingly causing the latter throu h the link 32 to raise or lower theouter end 0 the extension 31 to correspond with the change ofwater-level in the box 13 and thus var the head of the solution in theextension in accordance with the variation of head in the water=box, sothat as the rate of now through the slot 18 changes under variation ofhead in the water-box, that of the solution through the slot 28 willvary correspondingly as the outer end of the extension 31 is raised orlowered under the action of the float. The surplus of the solutionoverflows from the open outer end of the rotatable extension into thereceptacle 26 whence it returns through the pipe 25 to the tank 22 andis saved.

the solution to the water in accordance with variation in the supply ofraw water to the apparatus; which constitutes the gist of my invention.This method forms the subject of my divisional application, Serial N 0.416,264, filed on the 17th day of February, 1908. The same result isaccomplished in substantially the same way by the modified constructionillustrated in Figs. 7 and 8: Therein the pipe 23 terminates at itsupper end in aT-cou ling 33 from one end of w chprojects a rigi angularand tubular arm 29, the outer section extending by preference verticallyand containing a lateral erpendicular clon ated discharge-slot 28 or thesolution, w rile at the opposite end of the coupling is rotatably suported in alineinent with the rece tacle 26, t irough the medium of astuflingox 30", or packed-joint, the angular extension 31 similar to theextension 31 and like the latter havin a link-connection 32 with thelever 16. with this construction raising or lowering of the extension31" under the action of the float correspondingly chan es the head ofsolution therein (any overiiow of the solution falling into thereccptacle 26), the level of the solution-in the extension, whatever itsposition, being necessarily the same as the level thereof in the arm29".

What I claim as new and desire to secure by Letters Patent is 1. in awater purifying apparatus, the combination with a )rccipituting-tank, ofa watcr-box having a fixed discharge and containing a float, a reagcntsupply pipe having a fixed discharge, and a niovably-supportod tubularcxtcnsion of said pipe forming an ovcrflow for the rcagcnt-supply andopcrativcly conncctcd with said float, for the purpose set forth.

2. In a water purifying apparatus, the
